<p>A protection circuit includes a first to a forth switch device. The first switch device is connected to a first and a second cable line which are connected to a battery in a first node and controls switching for transmitting the second voltage of the second cable line to the first node. A second switch device is connected to the first node and a ground terminal and controls switching for supplying the voltage of the ground terminal. A third switch device is connected to the second switch device, the second node, the first cable and controls switching for transmitting the first voltage of the first cable line to the second node. The fourth switch device is connected to the second node, the first cable line and the output terminal of the first convertor, and controls switching for transmitting the first power of the first convertor to a battery.</p> |
